Are metals an endangered species


  • Anonymous


Scientists at the Henry Krumb School of Mines at Columbia University in New York examined many possible scenarios for mineral and metal conservation and concluded that ‘industry will have to be persuaded by social and legal pressures of the necessity–even at the expense of short term profits–to design reliable and durable products with a view to recyclability.’

In examining various estimates of the extent of the coming mineral crisis, John K. Tien, professor of metallurgy, and Richard M. Arons and Roy W. Clark, students at Columbia, began with criticisms of mineral exhaustion estimates such as those published in Limits to Growth by D. H. Meadows, D. L. Meadows, J. Randers, and W. Behrens (see Table 1).
